Lorelei was always going to be difficult, as 4 out 5 of her Pokemon were Water, but I never realised just how difficult it was going to be! So, she sent out Dewgong and I sent out Flicker. I used Toxic to try to slowly kill her and I used Flamethrower to help this process. However, this didn't work very well, so I switched to Solita and after surviving a Surf, defeated Dewgong with a Crit Hit Solarbeam!
I kept Solita out for Cloyster and, as he used Hail, I tried to use Stomp and Solarbeam. Again I struggled, so I switched to Flamethrower. The STAB helped me to win.

Next up was Lapras, the Pokemon I was most worried about. I sent out Fiera and used Extremespeed and Overheat to get Lapras down to red health. However, Lapras's Sitrus Berry partly healed her, before the Surfs became too much for Fiera to handle. With 1 down, I switched to Volcano who used Rock Slide to defeat Lapras!
However, Slowbro was next and he wrecked havoc through my team, the resistance to Fire and excellent Special Defence being the key reasons why I struggled. I kept Volcano out and tried EQ, which did virtually nothing! Slowbro simply Surfed him away. Next, Solita and her Stomp was more effective, but when Slowbro was on red health Lorelei healed. To make matters worse, Solita's Bounce missed and she was killed by Surf. I was three Pokemon down by this point and I hoped that Flicker could change my fortunes. Just as Slowbro used Amnesia, I used Toxic and then Bite to give me the advantage. With many healing items, I hoped I could keep healing Flicker from Surf, as Toxic sent Slowbro to the grave. Unfortunately, a critical hit killed Flicker and I was in trouble now. I switched to Ember and Double-Edged Slowbro down to red health again, whist surviving Surf. Thinking that Lorelei will use a Full Restore, I used Will-o-Wisp, but instead Surf killed Ember to bring me to my last Pokemon - Larva. Thankfully Larva didn't have to do anything as Toxic finally killed Slowbro.
Last up, Jynx suffered an OHKO from Larva's Flamethrower. THANK GOD!
